Basic Authentication service called By Zuul

不羁岁月 提交于 2019-12-01 10:58:21
I'm Zuul as edge server. so all request pass by this edge server. I have a micro-service A. all web services of A are protected by Basic Authentication. How can we call the services of A b passing by Zuul proxy? Should I add header for messages? Ideally the requester would have the token in the request. If you want to have Zuul add the authentication token then you can create a ZuulFilter and use: context.addZuulRequestHeader("Authorization", "base64encodedTokenHere"); Doing this would give open access to the services - which may not be wise. This is my Zuul filter: public class

Using K8S deployment, our project is based on springcloud. I want to know that in K8S, because the multi-node deployment passes the default host name of the registry, the gateway is deployed in A, and the config is deployed in B. They can't access each other through eureka before. I changed to eureka.instance.prefer-ip-address: true , but I found that they can only access each other on the same host. He is not using cluster-ip of K8S. I want to know how to access each other between services in K8S. In version 7-201712-EA of Activiti Cloud we provided an example using services running the

Difference between Spring Cloud Vault and Spring Cloud Config with Vault backend

问题 What is the difference between the followings? Spring Cloud Vault - http://cloud.spring.io/spring-cloud-vault/ Spring Cloud Config Server with Vault backend - http://cloud.spring.io/spring-cloud-static/Camden.SR4/#_spring_cloud_config_server 回答1: Spring Cloud Vault is more lightweight because it does not require to run a java server (Spring Cloud Config Server) as a frontend for Vault, your Spring Boot app connects directly to Vault. I have a small demo: https://github.com/gmarziou/demo

Spring cloud - how to get benefits of retry,load balancing and circuit breaker for distributed spring application

I want the following features in spring-cloud-Eureka backed microservices application. 1) Load balancing - if I have 3 nodes for one service, load balancing should happen between them 2)Retry logic - if one of the nodes did not respond, retry should happen for certain number ( eg 3. should be configurable) before falling back to another node. 3)circuit breaker - if for some reasons, all the 3 nodes of service is having some issue accessing db and throwing exceptions or not responding, the circuit should get open, fall back method called and circuit automatically closes after the services

Spring Cloud Stream message from/to JSON conversion configuration

I am using Spring Cloud Stream, with RabbitMQ binder. It works great with byte[] payload and Java native serialization, but I need to work with JSON payload. Here's my processor class. @EnableBinding(Processor.class) public class MessageProcessor { @ServiceActivator(inputChannel = Processor.INPUT, outputChannel = Processor.OUTPUT) public OutputDto handleIncomingMessage(InputDto inputDto) { // Run some job. return new OutputDto(); } } InputDto and OutputDto are POJOs with Jackson annotations. How do I configure JSON conversion strategy? How should message headers look like to be accepted and

SpringCloud学习笔记

SpringCloud是一个基于SpringBoot的微服务框架,它为开发人员提供了快速构建分布式系统中常用的模块。 架构图 在微服务架构中,需要几个基础的服务治理组件,包括服务注册与发现、服务消费、负载均衡、熔断器、智能路由、配置管理等,由这几个基础组件相互协作,共同组建了一个简单的微服务系统。一个简单的微服务系统如下图: 服务列表 spring-cloud-dependencies -->统一依赖管理 spring-cloud-eureka -->服务注册与发现 spring-cloud-config -->服务配置中心 spring-cloud-provider -->服务提供者 spring-cloud-client-ribbon -->服务消费者 spring-cloud-client-feign -->服务消费者 spring-cloud-zipkin -->服务链路追踪 spring-cloud-zuul -->服务网关 spring-cloud-admin -->服务监控 大合照 下面,我来解释一下这些服务哈... 1.服务注册与发现 Eureka,是 Spring Cloud Netflix 一个高可用的组件,向Eureka注册的实例需要向注册中心发送心跳(没有心跳连不上就当你挂了)。因此需要Erureka Server充当注册中心,然后将很多个Erureka

How to override the ribbon.serverListRefreshInterval default value in Spring Cloud Ribbon?

问题 I wrote a simple Spring Cloud Ribbon application, to call a REST service which was registered in Eureka. But how to override the ribbon.serverListRefreshInterval value? The default value is 30 seconds, I'd like to reduce the time interval. Thanks in advance. 回答1: Try with: myService.ribbon.ServerListRefreshInterval=10000 where myService is the name of your destination microservice. UPDATE : After some source code digging I found out that LoadBalancerBuilder calls: @Deprecated public
